UNITED STATES PATENT OFFICE;

JOHN HAWKSLEY, OF PHILADELPHIA, PENNSYLVANIA.

IMPROVEMENT IN PROCESSES OF FILLING AND FINISHING HARD WOODS.

Specification forming part of Letters Patent No. 184,618, dated November21, 1876; application filed September 14,1876.

of the wood, and imparting a smooth and fin-.

ished surface thereto, as hereinafter fully set forth. 4 I

In treating hard woods according to my improvement I first fill thepores with my No. 1 or filling compound, the composition of which is asfollows: Sifted whiting, one and onefourth pound; raw linseed-oil, onegill; Japan drier, a half tea-spoonful turpentine, one gillto be stirredtogether until thoroughly mixed.

Any suitable pigment or coloring matter may be addedas, for example,when used on oak or ash, a half tea-spoonful chrome-yellow, ground inoil, and one tea-spoon ful yellow ochre, ground in oil; for walnut orother dark wood, one tea-spoonful burnt umber and a half teaspoonfulburnt sienna.

The No. 1 compound is to be applied to the wood with a paint-brush, andallowed to stand until the gloss has'entirely left it-say, not less thantwenty minutes-after which the wood is to be rubbed with a piece of ragacross the grain, and afterward with a clean rag lengthwise of thegrain, to remove any superfluity of the compound.

About twelve hours after the application of the No. 1 compound I applyanother coat of the same, having previously added thereto about one anda halt. gill turpentine and one table-spoonful Japan drier. This willcomplete the operation of filling the pores, and, after the lapse of,say, twelve hours, will render the wood suitable for the reception ofthe finishing or No. 2 compound, which is composed of Japan drier, onegill; turpentine, one gill and inside varnish, one-third gill; to bemixed together and applied with a clean brush. Outside varnish alone maybe used as a finish in place of No. 2 in some instances.

By my improvement hard woods can be finished in much less time than bythe tedious process ordinarily practiced of applying from four to sixcoats of shellac, and rubbing with sand-paper after each coat, andwithout risk of injury from sun and rain.

I claim as my invention and desire to secure by Letters Patent- Y Theprocess of finishing hard woods, which consists in applying successivecoatings of a filling compound, consisting of whiting, linseed-oil,turpentine, and Japan drier, and a finishing compound consisting ofJapan drier,

turpentine,"and inside varnish, substantially in the manner herein setforth.
